FOLIAR APPLICATION OF PHYSIOLOGICALLY ACTIVE SUBSTANCE WHEN CULTIVATING SPRING SOFT WHEAT IN THE NORTH KAZAKHSTAN REGION

Spring wheat is one of the oldest and most common crops on the globe. The use of various biologically active drugs can improve the quality of the grown grain, as well as increase its yield. One of these drugs is an extract developed by the doctor of chemical sciences V. Polyakov, from balsamic poplar buds.
This work is devoted to the use of a physiologically active substance – Polyakov extract, as a foliar top dressing for the cultivation of spring soft wheat of Omskaya 19, which is the most popular in the North Kazakhstan region. There was a study of the effect of the substance on the growth, development and productivity of spring wheat. The studies were carried out in three experimental sites. As a result of the studies, it was found that the extract has a beneficial effect on the productivity of the grain. The yield increment averaged 29 %, which allows us to recommend this substance as a non–root dressing for growing various plant cultures.
